This last post was a bit hard to follow, but by pushing in the clutch and letting the engine speed idle down, you are taking the engine, flywheel and pressure plate out of the equation temporarily. If the vibration remains, it indicates the issue is in the transmission, driveline or rear end.

If it's still the same (vibrating) it's one of these trans, driveline or rear end.. Really is not telling me much as I don't think it can be much more than that, aside maybe a wheel balance issue or front end.
What I was thinking was if it doesn't do the vibrating when the clutch is engaged at least I'll know it's not a trans problem or driveshaft etc...i know it's probably the tranny or driveline most probably.
I was just trying to see thru a process of eliminatio, I would be able to narrow it down batten those 3 main issues. That's all.
Thanks for your input as well, will see if I will get it done on the weekend.
Have a good day..
